Insulative and cushioning interliner for garments and the like

Abstract

A durable, light-weight interliner exhibiting enhanced insulative and cushioning properties is produced from a blend of approximately equal parts of a thermoplastic elastomer and an ionomer foamed by a normally gaseous expanding agent.

What is claimed is: 
     
       1. Insulative and cushioning interliner for garments and the like comprising a fine closed cell foam produced from a foamed blend of approximately equal parts by weight of an ethylene/methacrylic acid copolymer based ionomer resin and a styrene-butadiene block copolymer wherein said foamed blend is expanded by a normally gaseous expanding agent comprising dichlorotetrafluoroethane. 
     
     
       2. The interliner of claim 1 wherein said foamable blend includes from about 0.1% to about 40% by weight of a polyolefin. 
     
     
       3. An insulative and cushioning interliner for garments and the like comprising a fine, closed cell foam produced from a foamable blend of an ethylene/methacrylic acid copolymer based ionomer resin, a styrene-butadiene block copolymer, and a polyolefin, wherein said foamable blend is expanded by a normally gaseous expanding agent comprising dichlorotetrafluorine, said ionomer resin and block copolymer being present in said blend in approximately equal parts by weight and comprising from about 40% to 100% by weight of said blend, said polyolefin comprising from about 0% to about 40% by weight of said blend.
